A gas generator (10), in particular for a safety device in vehicles, comprises a pressure chamber (22) which is filled with compressed gas (24) and which is closed off from an environment of the gas generator (10) by a membrane (16). The compressed gas (24) contains a gaseous oxidant, which is composed predominantly of oxygen. The pressure chamber (22) receives a solid fuel (31), wherein the compressed gas (24) is in direct contact with the fuel (31) before the gas generator (10) is activated. When the gas generator (10) is activated, an igniter (14) separated pressure-tightly from the pressure chamber (22) triggers a conversion of the gaseous oxidant with the solid fuel (31), with heat being generated. The fuel (31) is in the form of a gas-permeable fuel body (32) made up of one or more fibers, and the molar fraction of the gaseous oxidant in the compressed gas (24) is at least 1.1 times the amount of oxidant required for a stoichiometric conversion of the gas-permeable fuel body (32). A module and a vehicle safety system comprise such a gas generator.

    一种气体发生器(10),尤其是用于车辆中的安全装置的气体发生器,包括填充有压缩气体(24)的压力室(22),该压力室通过隔膜(16)与气体发生器(10)的周围环境封闭。压缩气体(24)包含气态氧化剂,该气态氧化剂的大部分由氧气组成。固体燃料(31)被容纳在压力室(22)中,其中压缩气体(24)在气体发生器(10)被激活之前就与燃料(31)直接接触。以压力密封方式与压力室(22)分隔的点火器(14)在气体发生器(10)被激活时触发气态氧化剂与固体燃料(31)的反应,从而产生热量。燃料(31)呈由一种或多种纤维组成的透气性燃料体(32)的形式存在,并且气态氧化剂在压缩气体(24)中的摩尔比例至少是透气性燃料体(32)的化学计量反应所需的氧化剂量的1.1倍。一种模块和一种车辆安全系统包括这种气体发生器。
